Such a wonderful experience with this Doctor Ashtiani! He was on time, warm, friendly, and never made us feel rushed. It was obvious he had reviewed my mom’s chart beforehand, he knew her medications and health history and came prepared.
What we appreciated most was how genuinely caring and thorough he was. He asked about her overall health, listened carefully, answered all of our questions, and even made sure she didn't need any medication refills.
We wish all doctors were this knowledgeable, patient, understanding, and kind. We felt truly cared for and are so grateful to have him as my mom’s cardiologist!

Front office is very professional in all aspects, particularly Gabby who makes and schedules appointments and procedures.
Doctor Ashtiani exceeds expectations - excels at articulating cardiology concepts. He is an incredible doctor who consistently spends major league time with me. He listens attentively, answers all questions and reviews in detail related reports of previous treatment protocols, tests and procedures - high level of intellect combined with significant communicative abilities along with vast knowledge and experience - also a really nice guy who cares about his patients.
